I feel for you. I'm sure you are a much better turner than I am.
I combined a pump,1 hp motor, pressure switch, some small pipe fittings, gauges & pressure control valve with a 50 gallon hot water tank & have a pretty good compressor. Cost the pressure switch & a few pipe fittings. I questioned a plumber/electrician friend & showed him the system he said it was safe & that the burst point for the tank was way higher than I run it to.
